Using a white screen serves various practical and creative purposes. It is often used as a clean, distraction-free background for photography, videography, or graphic design, helping subjects or products stand out clearly. White screens are also valuable in display and color calibration, ensuring true color accuracy across monitors and devices. In lighting setups, a white screen can reflect light evenly, creating a balanced, neutral effect. Additionally, white screens can function as simple light sources on digital devices, offering a quick way to illuminate a dark environment or test screen brightness and contrast settings.
